j Application filed October 22,1901. Serial No. 79,510. model-h isticsof simplicity, cheapness, compactness,

efficiency, and convenience in use.

The invention comprises, essentially, a pair of coacting serratin gdevices,preferable in the form of rollers, having serrated surfaces, the

rollers being pivoted in a suitable frame or support capable of beingmanipulated in such manner as to compress the paper between the rollersand by a movement of the latter relative to the former to produce on itis desired to protect.

the paper a band of indentations of any desired length coextensive withthe words or figures which it isdesired to protect from alteration.

To accomplish effectually the purposes of the invention, it is desirablethat the serrations should be such as to produce a permanent distortion,abrasion, bruising, or straining of the .fibers of the paper which couldnotloe obliterated by smoothing or other treatment of the indentedparts.

The invention may be embodied in many difierent forms. In the simplestform contemplated the inarker-frame consists of a single piece ofspringmetal bent upon itself and having the rollers journaled in therespective ends thereof, the axes of the rollers being either parallelwith the frame or transverse thereof. In this form the rollers standnormally a slight distance apart, so that the paper can be introducedbetween them. The user then presses the rollers firmly together and bymoving them relative to the paper indents or serrates the portionthereof which The bifurcated frame may consist of rigid arms pivoted af5o ter the manner ofa pair of shears and may be combined with a springacting either to bring the rollers together or to separate them. Othermodifications of form will suggest themselves to skilled mechanics.

It is obvious that in order to perform properly the desired operationthe serrations of one roller must intermesh with those of. the other.would yield sufficiently to furnish the slight lateral displacementnecessary for this purpose; but itis preferred to give the rollers a.

slight freedom of'movement axially in their bearings. The points of theserrations of one or both rollers may, if desired, be sufficiently sharpto puncture the paper; but this is notregarded as essential to the endin view. I

The invention includes an inking attachment adjustable with relation toand acting is a side view of a construction differing in detail fromthat of the other figures.

In Figs. 1, 2, and 3 the frame 1 is formed of a strip of resilient metalbent on itself and having ears 2 integral therewith. The ears have holes3 and act as bearings for the trunnions l of the rollers 5, said rollershaving serrated or otherwise roughened surfaces which indent the paperincontact with which they are pressed. The rollers have slight axialmovement in the bearings in order to permit the meshing of the milledsurfaces when pressed into contact or against paper inter.- posedbetween said rollers. On one arm of the frameis a depression 9 forengagement of the thumb of the user. The inking attachment comprises aplate 6, having its ends turned under to embrace the edges of the frame.The plate is slidable on the frame Ordinarily the members of the framethe arms.

and can be moved by means of the thumb of the operator. Arms 7, formedwith the under-turned ends of the plate 6, act as bearings for theinking-roll 8, said inking-roll being of any suitable construction tocarry ink and having trunnions journaled in the bearings of Theserrating-roller acts on the paper on a plane considerably below that ofthe inking-roll in order that the paper operated upon may not bediscolored through contact with said inking-roll.

In the modification shown in Fig. 4 the rollers are mounted on the endsof two arms A, having a pivotal connection B, the extensions beyond thepivot serving as handles. A spring between the extensions tends to pressthem apart. In using this device the rollers are separated forintroduction of the paper by grasping the handles and are broughttogether to act on the paper by the pressure of spring 10. Theinstrument would obviously be operative without the spring.

Having thus fully described the invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. Apaper-markercomprising a frame, and two serrating-rollers mountedthereon adapted to be moved into cooperative rotation by the hand of theuser and having pointed teeth adapted to permanently distort the surfaceof the paper acted on.

2. A paper-marker comprising two arms movable'by the hand of the user,and two ('20- acting serrating-rollers placed opposite each other on thearms and having pointed teeth adapted to permanently distort the surfaceof the paper acted on.

3. A paper-marker com prising a bifurcated frame, the two arms of whichare movable by the hand of the user, and two coacting serrating-rollersjournaled one on each arm and having pointed teeth adapted topermanently distort the surface of the paper acted on.

4. In a paper-marker, a frame comprising a strip of metal bent on itselfand having ears integral therewith, and paper roughening rollersjournaled in the ears.

5. In a paper-marker, afranie comprising a strip of metal bent on itselfand having ears integral therewith, rollers journaled in the ears, aplate movable on the frame and an inking-roller carried by the plate.

6. In a paper-marker, a bifurcated springframe, bearings on each end ofthe frame, and rollers having serrated surfaces, journaled in thebearings.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
